Bug introduced in 8 or earlier and fixed in 13.0
Whenever the blue line drops below the orange one MMA (10.0) inserts two additional plotmarkers:
ListLinePlot[
{
{12., 13., 6., 16., 15., 12., 7., 15., 15., 17.},
{9., 9., 9., 9., 9., 9., 9., 9., 9., 9.}
},
Filling -> {1 -> {2}},
Frame -> True,
FrameTicks -> {{Automatic, None}, {Automatic, None}},
GridLines -> {Range@10, Automatic},
PlotMarkers -> Automatic,
PlotRange -> {{1, 10}, Automatic}]
Without the Filling
- option the additional points don't show up:
ListLinePlot[
{
{12., 13., 6., 16., 15., 12., 7., 15., 15., 17.},
{9., 9., 9., 9., 9., 9., 9., 9., 9., 9.}
},
Frame -> True,
FrameTicks -> {{Automatic, None}, {Automatic, None}},
GridLines -> {Range@10, Automatic},
PlotMarkers -> Automatic,
PlotRange -> {{1, 10}, Automatic}]
Is this a bug?
Is there a workaround?
Mesh -> Full
gets rid of the unwanted markers (v9 windows 8). $\endgroup$Filling
results in extra points included into the plotted lines (what was confirmed as an issue by rcollyer). So I add the bugs tag. $\endgroup$Mesh->Full
also works =) $\endgroup$
